The ATM configuration algorithm is based on configuration in AutoNet  and is comprised of two phases, monitoring and topology acquisition. The monitoring algorithm watches links for changes in up/down status. It incorporates a mechanism for damping oscillations between states which may be even more useful for a radio environment than for the fixed network environment for which is was designed. The topology aquisition phase propagates neighborhood information from each switch to a root node, which then distributes the result back to all nodes. A mechanism is included to handle recurrent topology changes. The latest change is given priority, thus earlier propagation phases die out, before the latest one ends.
